feather river redd survey locations qc

Goal of this document is to review the Feather River redd survey locations and the locations where redds were observed. Main goals:

Identify redd points that are off survey locations
Identify locations per year that did not have redds recorded

Summary of notes and observations of this markdown:

Survey location names and redd locations are inconsistent, this could be a spelling difference, or similar words. Question: is it worth spending time on unifying names across these two data sets?
Observations:
There a lot more survey location names on the redd survey data, than the actual site names (some might be simply different spelling)
Most of the redd sites that are “off” a site location are off
- There are some redds conglomerated in the stream that do not fall within a survey site, however they all have “great western” as location (between Upper Robinson and Aleck). Question: are we missing that site from the survey’s sites?
Similar that previous point for “lower vance east/lower vance”

Map with survey locations and redd data by year

Note: Survey location names and redd locations are inconsistent, this could be a spelling difference, or similar words. Question: is it worth spending time on unifying names across these two data sets?

Looking at redds per year. Listing those years when there were not redds in all locations.

Survey locations that do no have Redds - by year

List based on observations on map (this means redd points might no be exactly inside the survey location polygon, but close to it, and location name matches). Is it worth doing this check for all of them right now?

Note: the site name is “lower big”, redd location name “big riffle” - big riffle redds are located on both “lower big” and “Big” - redds located on survey location “Lower hour” are hour, lower hour and upper hour - upper hour survey location has only two redds with location name “hour” - G95EastSideChannelBottom has 1 redd under upper hour name

Note: there is a redd on “g95 main” but survey location names are: G95WestSideChannel, G95EastSideChannelTop and G95EastSideChannelBottom. Question: where does that point belong to?

Filtering those redds that are off survey locations

Observations:
- There a lot more survey location names on the redd survey data, than the actual site names (some might be simply different spelling)
- Most of the redd sites that are “off” a site location are off
- Locations that are off-channel and hard to relate to survey sites:
  - Location: lower auditorium, Date: 2015-10-29, Survey Week: 7-3
  - Location: lower auditorium, Date: 2015-10-22, Survey Week: 6-4
  - Location: top of auditorium, Date: 2015-11-24, Survey Week: 11-1
  - Location: upper hatchery riffle, Date: 2014-10-22, Survey Week: 7-2
  - Location: upper hatchery riffle, Date: 2014-10-02, Survey Week: 4-3
  - Location: table mountain, Date: 2015-09-22, Survey Week: 2-2 (close to table mountain location but off channel)
  - Location: top of auditorium, Date: 2014-10-20, Survey Week: 7-1
  - Location: top of auditorium, Date: 2014-10-14, Survey Week: 6-1
  - Location: lower auditorium, Date: 2015-10-19, Survey Week: 6-1
  - Location: middle auditorium, Date: 2015-10-22, Survey Week: 6-4
  - Location: upper hatchery, Date: 2015-10-28, Survey Week: 7-2
  - Location: mid auditorium, Date: 2014-11-13, Survey Week: 8-2
  - Location: moe’s side channel, Date: 2015-10-09, Survey Week: 4-4
  - Location: moe’s side channel, Date: 2015-10-30, Survey Week: 7-4
- Locations that are very off distance from stream
  - Location: lower auditorium, Date: 2014-10-01, Survey Week: 4-2 (located north from river, at Lake Orville)
  - Location: lower auditorium, Date: 2014-09-18, Survey Week: 2-2
- All others are geographically closer to at least one of the sites
- There are some redds conglomerated in the stream that do not fall within a survey site, however they all have “great western” as location (between Upper Robinson and Aleck). Question: are we missing that site from the survey’s sites?
- Similar that previous point for “lower vance east/lower vance”
